Warm, nurturing parents may pass along strategies for building and maintaining positive relationships to their kids, setting them up for healthier, less-violent romantic relationships as young adults, according to researchers. In a study, adolescents who reported a positive family climate and their parents using more effective parenting strategies tended to go on to have better relationship problem-solving skills and less-violent romantic relationships as young adults.

About one in every 100 people in the world takes glucocorticoids long term to treat immune-mediated diseases. However, glucocorticoids, such as prednisone, have a side effect -- they induce glucocorticoid-induced bone loss, causing an estimated yearly bone fracture rate of 5 percent. An alternative treatment option to the standard treatment now appears promising, according to an international study. Researchers compared the monoclonal antibody denosumab against a standard bisphosphonate.

Biomedical engineers have developed a new technique for measuring blood flow in the human brain, which could be used in patients with stroke or traumatic brain injury, for example. The new technique, based on conventional digital camera technology, could be significantly cheaper and more robust than prior methods.

A research team has developed a simple, effective technique to enhance the power output of single-mode lasers that are 'surface-emitting' (as opposed to those using an 'edge-emitting' configuration). Of the two types, the surface-emitting configuration for semiconductor lasers offers distinctive advantages in how the lasers could be miniaturized, packaged and tested for commercial production.

Older adults are more likely to stick with a group exercise program if they can do it with people their own age, a new study has found. Working out with peers of the same gender doesn't seem to make a difference, which suggests that age-targeting but not gender-targeting should be considered when developing exercise programming.

Ammonia (NH3) has attracted attention in recent years as a carbon-free fuel that does not emit carbon dioxide. For use as a fuel, it should have a lower combustion temperature and produce only nitrogen (N2) and water. Now, researchers have succeeded in developing a new catalyst that burns NH3 at a low temperature and produces N2. The results are expected to contribute to climate change countermeasures and increased renewable energy use.

The reports on biodiversity are based on indicators that only take indigenous -- i.e. 'original' -- species into account for each region. Yet today modern environments are made up of indigenous and introduced species. The introductions are either deliberate or accidental. Although these introduced species play important roles, they are ignored by specialists, a fact that partly distorts the international nature reports. The study recommends that the contributions made by these species should be included.

Human herpesvirus 6 infects most people all over the world. It is usually well controlled by the body, but it can cause diseases in immunocompromised individuals. Scientists have now identified virus structures that can be attacked by killer T cells -- a possible approach for new therapies.

Researchers are at the forefront of analyzing how climate lawsuits shape the nation's response to climate change. A new analysis investigates the role of health concerns in climate litigation since 1990 and finds that although health is cited in a minority of cases, it may have critical potential for protecting communities from the effects of climate change and coal fired power plants.

Consumers consider online reviews important for choosing physicians, but they should be wary of using those ratings to choose plastic surgeons. The reviews tend to be polarized, and some are written by people whom consulted with the doctor but never had surgery, reports a new study.

Researchers found men with a stronger grip were more likely to be married than men with weaker grips. Grip strength was not a factor in the marital status of women. Grip strength is an established measure of health and has previously been linked to one's ability to cope independently and predicts the risk of cardiovascular diseases and mortality.

Planners should view high rugosity (highly non-concentric) urban areas as symptomatic of vigor in urban and agricultural markets. Greater planning efforts are required to coordinated the co-joined health of both agricultural and urban land-uses. Empirical analysis is supported by land-use policies from 30 case study counties.

Occurrence of Rift Valley Fever (RVF) has often been linked with El Niño rainfall. To curb future outbreaks of RVF, scientists have carried out enhanced syndromic surveillance of 22 high-risk RVF Kenyan counties to collect data on RVF-associated syndromes and risk factors in livestock from November 2015 through February 2016. Their research could provide the first step toward establishing a national syndromic surveillance system for livestock in Kenya.

A new mathematical model incorporates personalized details to simulate the metabolic effects of exercise. The model can be adapted to different individual characteristics, such as age and weight, as well as different types and intensities of exercise.

Within cells infected by Kaposi sarcoma herpesvirus (KSHV), the human protein CADM1 interacts with viral proteins to promote chronic inflammation, which plays a major role in the development of cancers caused by KSHV.

Biomedical engineers have demonstrated that metastatic cancer cells can reprogram their metabolism to thrive in new organs. Cells originating from colorectal cancer change their dietary habits to capitalize on the high levels of fructose often found in the liver. The finding offers both general and specific insights into new ways of fighting metastatic cancer.

A new article provides guidance for those intending to study ancient human remains in the Americas. The paper, written by Indigenous scholars and scientists and those who collaborate with Indigenous communities on studies of ancient DNA, offers a clear directive to others contemplating such research: First, do no harm.

Researchers report a new tool that engineers the CRISPR-based diagnostic SHERLOCK for rapid outbreak response. The platform can now be used to detect viruses directly in clinical samples such as blood or saliva, eliminating a processing step that previously required a lab and professionally trained personnel. The updates to SHERLOCK enable clinicians to quickly and cheaply diagnose patient samples and track epidemics with limited equipment.

A new study reports that New York City firefighters exposed to the 9/11 World Trade Center disaster site face an increased risk for developing myeloma precursor disease (MGUS), which can lead to the blood cancer multiple myeloma.

Researchers have discovered that an FDA-approved drug designed to treat cancer helps fight tuberculosis in mouse models. The drug is an MMP inhibitor designed to increase the structural integrity of blood vessels in tumors so that other drugs can reach inside them. It performs the same function in the granulomas associated with tuberculosis so that antibiotics can reach the bacteria sheltering within.

If there is one thing all cancers have in common, it is they have nothing in common. A new study has shed light on why proteins, the seedlings that serve as the incubator for many cancers, can vary from cancer to cancer and even patient to patient, a discovery that adds to a growing base of knowledge important for developing more effective precision therapies.
